To ((72 w lwm 2'2! may concern Be it known thatl, FREDERICK D. CRANE,

sures, of which the following is a specifi-- 'atlon.

This invention relates to receptacle closures, and it comprises a can or receptacle having an outlet opening, the edge of the opening being formed in the arc of a circle or other curvature, and a head or closure member pivotally mounted on said receptacle and adapted to cover the outlet opening, the upper face of said closure member being curved on a radius less than the radius of the curve formed on the edge of the out let opening, the closure member being eccentrically mounted with respect to said curved edge.

in theprescnt invention, it provide an improved inethod of closing collapsible tubes, cans, or boxes, in which tooth paste, shaving soaps, talcum powders, and the like, arepacked and which should be tightly closed when not in use, on account of the volatile nature ot' the constitutents. I further provide a closure which will not stick on account of the gummy ingredients often pres ent in the contents of the tubes or cans.

To attain this end, the can or tube is pro vided with a curved edge at the outlet opening, and a head or closure member is pivotally mounted over the outlet opening and provided with an upper surface curved on a slightly less radius. The closure memher is mounted eccentrically to the curva- Eure of the can top, whereby it is easily noved from the closed to the open position, mt when returned to the closed position, it engages the curved edge and then binds igaiust the curve or slope. The closing ac- ;ion incidentally wipes the surface of the outlet clean, and is maintained in closed 1. v.n by friction.

In the accompanying drawings, 1 have :hown ..e embodiment of the invention. Ln this showing:

Figure l is a side elevation with the clo- .ure member in closed position,

Figure 2 a similar view, parts being shown if? section, with the closure member n open csition,

Figus. is a detail perspective view of the closure member and a supporting ring therefor, and,

Figure 4 is a similar View of an alternate form of supporting member.

Referring to the drawings, the reference numeral 1 designates the container which may be a can, tube, or other receptacle of the type generally employed for packing tooth pastes, shaving powder, and talcum powders, or the like. The containeris provided with a neck 2, having an outlet opening As shown, the edge of the outlet opening is curved in the arc of a circle or other curvature. The center of the arc of the outlet opening is designated at 4.

A closure member 5 is pivotally mounted on the neck of the container, the pivot thereof being arranged slightly eccentric to the center of the curve 3, as shown at 6. The upper face of the member 5 is curved on the radius slightly less than the curvature of the outlet opening. The closure member is provided with a pair of ears or lugs 7, by means of which it is pivotallymounted on the neck of the container. A finger piece 8 is provided to permit opening and closing of the closure member. The earsare provided with openings 9, for the reception of pins or other fastening members.

A supporting ring 10 is suitably arranged on the neck of the container, andt-his ring is provided with oppositely disposed lugs or ears 11, having openings 12. The openings 9 and l2-are adapted to register with each other and to receive pivot pins to pivotally support the closure member.

In Figure 4 of the drawings, 1 have shown an alternate form of supporting member.

comprising a wire ring 13, having loops 14, for the reception of pivot pins. The ends of the wire are twisted, as at 15, to retain it in position.

The closure member maybe made of any suitable material, preferably of the same material as the tube or can, or other material which will not be attacked by the contents of the can. The supporting device may be secured on the neck of the container. in any suitable manner. A layer of cork or other suitable material (not shown) may be arranged on the inner face of the closure member, when the contents of the container are particularly liquid or volatile.

It is to be understood that the form of my invention herewith shown and described is to be taken as a preferred example of the same, and that various changes in the shape, size,- and arrangement of parts may be resorted to without departing from the spirit of the invention or the scope of the subjoined claims.

Having thus described my invention, I

' claim 1. The combination with a receptacle havmg an outlet opening, the edge of which 1s curved, of aelosure member comprlsmg a curved plate adapted to cover said opening,

the curvature of said plate being on a smaller radius than the curvature of the edge of the opening, a palr oi downwardly projecting ears carried by said plate, a ring,

curved plate adapted to fit over the outlet opening, the curvature of the plate being on a smaller radius than the curvature of the edge of the opening, and means for piv' otally mounting said closure member eccentrically of said curved edge.

3. The combination with a receptacle having anoutlet opening, the edge of which is curved, of aclosure member comprising a curved plate adapted to cover said opening, the curvature of said plate being on a smaller radius than the curvature of the edge of the opening, a pair of downwardly projecting ears carried by said plate, whereby the closure member is pivoted to the recep tacle, the pivots of said closure member be ing arranged ecoentrically of the center of said curved edge.

In testimony whereof I afiix my signature in presence of two witnesses.

FREDERICK D. CRANE.
